Original application filed October 27,1914, Serial No; 868,868. .Dividedand this application filed May l, 1916. Serial No. 94,764.

To all whom it may concern;

Be it known that I, J I'M PARKER, a citizen of the United States,residing at Tecumseh, in the county of Pottawatomie and State ofOklahoma, have invented a new and useful Raising and Lowering Device forAgricultural Implements, of which the following is a specification.

The present invention appertains to agricultural implements and this isa divisional application of the application for patent on a tree digger,Serial No.. 868,868, filed October 27, 1914:, now Patent No. 1,182,032,granted May 9, 1916.

It is the specific object of the invention to provide novel and improvedmeans for depressing and elevating the soil engaging blade of. themachine, which inthe present caseisillustrated as a tree digger,although it is to be understood that the raising. and lowering devicecan be used upon various agricultural implements.

With the foregoing and other objects in view which will! appear as thedescription i proceeds, the invention resides in the combination andarrangement of parts and in the detailsv of construction hereinafterdescribed and claimed, it being understood that Fig. 2 is a longitudinalsection thereof, 1

portions being broken away.

In carrying'outl the invention, there is provided: a sulky or wheelmounted: frame or body 1, which includes the upper rectangular section 2and. the'sidesections 3 attached thereto,-and including theffront andrear upright portions 1' and: 5,. respectively, and the longitudinalbars on members 6' connecting the'lowerends of the portions 4 and 5. Theframe 1 is thus of'invert'edi U shape or 'is arched transversely. f

A longitudinabtongue or pole 7 is bolted or otherwise secured upon theends of the top section 2 of the frame llintermediate the side sections3 of-the frame and: an arched axle 8' has" its upright portions securedwithin the sidesections 3: of the frame 1,

while the intermediate or crest portion of :the aXle 8 projects upwardlythrough the the frame 1. The a-Yle '8 is disposed intermediate the endsof the frame 1 to balance the machine. a

The shovel or digging blade 10 is of U- shapc, and is carried by apairof forwardly projecting and diverging beams I 12 which have their rearends securely riveted or otherwise attached to the upper ends of theshovel 10, while the forward ends of the beams 12 are loosely connectedto the lower protruding ends of the standards or uprights i of the frame1, by means of short chains or links 13. The beams 12 are arranged-atobtuse angles with the shovel 1-0, asclearly seen in Fig. 2, whereby theintermediate or lower portion of the shovel will be arranged at an acuteangle with respect to'the beams12. The beams 1-2jlie below the frame 1and the axle 8, whereby the shovel .will be carried below the rearportion-of end of theframe, and the chains or other fie xiblcj'elements19 are attached to the points of junctureof the beams 12 and the shovel10 and are secured to the shaft 18 to be woundthereon. A- suitable handlever 20 is fulcrumed looselyupon the shaft 18 adjacent the'rightzhandside of the frame 1 and carries a-lower'springpressed pawd or dog 20engageable with a-ratchet wheel llkeyed or otherwise secured upon'theshaft 18, and apawl or: dog-22is carried by the right hand sideoftheframe to engage the ratchet wheel 21 for: normally preventing theretrograde or reverse rotation of; the said shaft.-

The meohanismfor depressingthe shovel lO'an'd maintainingthe same indepressed positiom-embodies apair of U-shaped clips 23 straddling thebeams 12 from below and adj ustably secured to the said beams adjacenttheir rear ends or the shovel 10, and a pair of thrust rods 24 havetheir lower ends pivoted between the ends of the respective clips 23 andhave chains or flexible elements 25 detachably connected totheir upperends. The lower ends of the chains 25 are secured to and adapted to bewound upon a transverse winding shaft 26 terminally ournaled to thesides of the top sections 2 of the frame immediately in advance of theshaft 18. The thrust rods 24 project above and are adapted to restrearwardly against the shaft 26, in order that when the chains 25 arewound upon the shaft 26, the thrust rods 24- will be forcibly depressedto swing the beams 12 downwardly. The shaft 26 may be convenientlyrotated through the medium of a suitable hand lever 27 loosely fulcrumedupon the shaft 26 adjacent the left hand side of the frame 1, andcarrying a spring pressed pawl or dog 27 engageable with the ratchetwheel 28 secured upon the shaft 26. A pawl or dog 29 is carried by theleft hand side of the frame 1 for engaging the ratchet wheel 28 toprevent the reverse rotation of the shaft 26 under normal conditions.

The operators seat is carried by the rear end of the frame 1 and liesbetween the right and left hand levers 20 and 27 which may be readilymanipulated by the operator, and which afford considerable purchase inrotating the shafts 18 and 26, respectively.

The machine is adapted to be drawn over the ground by a plurality ofhorses, mules or other draft animals.

In operation, when the machine is being drawn over the soil with theframe 1 running astride a row of young trees, the shovel or diggingblade 10 may be forcibly depressed into the soil to loosen the trees orplants and lift them up by their roots. To depress the shovel, thethrust rods 24: are pressed downwardly and the upper or free ends of thechains 25 are engaged. to the upper ends of the rods 2-1, in which eventthe winding shaft 26 is rotated in the proper direction by oscillatingthe hand lever 26, so as to wind the chains 25 upon the shaft 26 toforcibly depress the beams 12 and to hold the said beams in a loweredposition. The inclination of the intermediate portion of the shovel withrespect to the beams 12, will give the shovel a natural tendency to workits way into the soil below the surface thereof, so that the shovel maybe conveniently depressed, especially due to the fact that the handlever 27 being operatively connected to the shaft 26 through the pawland ratchet device, will afford a considerable pin-chase for depressingthe beams 12.

The forward edge of the shovel 10 being sharpened will enable the shovelto cut its way through the soil in a convenient and ready manner, underthe plants or trees. The intermediate portion of the shovel will outunder the plants, while the sides or arms of the shovel will loosen orsever the soil at the sides of the row of plants being dug.

To raise the shovel out of the soil, as when the machine is runningidle, or when the machine is turned around at the ends of the rows, thepawl or dog 29 which holds the shaft 26 against reverse rotation, is released from the ratchet wheel 28, and the hand lever 20 is thenoscillated to wind the chains 19 upon the winding shaft 18, which willraise the rear ends of the beams 12 to elevate the shovel blade abovethe surface of the soil. The pawl or dog 22 engaging the ratchet wheel21 of the shaft 18 will hold the shaft 18 against retrograde movement,to prevent the chains 19 from unwinding, until the pawl or dog 22 isreleased for enabling the shovel to be depressed by the actuating handlever 27 as above intimated.

WVith the present apparatus, it is an easy matter for the operator todepress and elevate the shovel, as desired, and in this manner, thelabor of digging the trees or other plants is reduced to a minimum. Theother advantages and capabilities of the present device will be obviousto those skilled in the art, without further comment being necessary.

Having thus described the invention, what is claimed as new is:

1. In a device of the character described, a riding frame, a beamloosely connected thereto and having a blade, a winding member carriedby the frame, a thrust rod connected to the beam, and a flexible elementconnecting the thrust rod and winding member.

4. In a device of the character described, a riding frame, a beam havingits forward end loosely connected thereto and having a blade at its rearend, a pair of winding shafts carried by the frame transversely thereof,a thrust rod having its lower end pivotally connected with said beamadjacent the rear end thereof and projecting upwardly above one of saidshafts, a flexible element connecting said shaft and upper end of saidrod, a flexible element connecting the other shaft and beam adjacent therear end thereof, a hand lever pivotally mounted upon each shaft, aratchet wheel secured upon each shaft, a pawl carried by each hand leverand engageable with the respective ratchet wheel, and pawls carried bythe frame and engageable with the ratchet wheels.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
